獲取本機IP地址
1 CString sLoginUser;
2 CString sLocalIP;
3 WORD wVersionRequested;
4 WSADATA wsaData;
5 wVersionRequested = MAKEWORD( 2, 0 );
6
7 if ( WSAStartup( wVersionRequested, &wsaData ) == 0 )
8 {
9 sLoginUser.TrimLeft();
10 sLoginUser.TrimRight();
11 sLocalIP = CCommonFun::ConvertHostNameToIP(sLoginUser);
12
13 WSACleanup( );
14 }
在CCommonFun類中：
1 CString CCommonFun::ConvertHostNameToIP( const CString &sHostName )
2 {
3 CString sIP;
4
5 HOSTENT *host_entry = gethostbyname(sHostName);
6 if( host_entry != 0 )
7 {
8 sIP.Format("%d.%d.%d.%d",
9 (host_entry->h_addr_list[0][0]&0x00ff),
10 (host_entry->h_addr_list[0][1]&0x00ff),
11 (host_entry->h_addr_list[0][2]&0x00ff),
12 (host_entry->h_addr_list[0][3]&0x00ff));
13 }
14
15 return sIP;
16 }
